T 0 all! whom it may concern: I

Be it known that I, Dr. GU'sTAv A. BRUHN, residing at Harburg-on-the-Elbe, Germany, a citizen of the German Republic, have invented a certain new and useful Improve ment in Stop Mechanism for Registers, (for which I have filed an application in Germany; Oct? 30,"1917,) of which the followin is a specification.

his invention relates to a stop mechanism for registers which is brought to a standstill when a fixed number of weighings have been carried out. This is particularly necessary when filling receptacles with the treated material, in order to prevent them from being filled to excess or overloaded. I

The invention consists in adapting to an apparatus of this kind a counting or stopping apparatus, which can be set to a previously determined number of weighm s.

Such apparatus, in which adjustable gure dials are set in motion by means of a ratchet mechanism and when the number for which the apparatus has been set is reached a lever which throws the mechanism out of operation passes through a'gap in the figure dial and brings the whole machine to a standstill, are already known 1n various forms.

The present invention differs from those appliances of the same kind hitherto known by the simplicity of its entire construction and also of its several parts, the present apparatus consisting in the main of only a number or figure dial, a disk with a beaded edge and a stopping pawl or a stopping lever which is suspended from and slides over this edge. In the edge is cut a. gap into which the sto ping lever drops, as soonas the number oFweighings for which the apparatus has been set, have been carried out.

The number of weighings at the particular time can also be ascertained at any time from this figure disk.

The invention will be further described with reference to the accompanying drawings which show an example of construction of the invention.

Figure 1 is a front elevation and Fig. 2 is a section on the line A--B.

To an angle piece a which is mounted on the main apparatus, is afiixed a carrier 6, to which is connected a spindle c, on which spindle c is mounted to rotate a toothed disk d, the number of teeth on which can be ascertained and read off on a series of scale divisions and numbers. In front of this disk d is placed another rotating disk 6, which has a flanged edge 7. On this flange is mounted a pointer g, to which a pointer 71. mounted on the .carrier 6 corresponds. The pointer g has opposite it a gap 71.

The. connection with the stopping lever of the driving mechanism of the main apparatus is effected by a locking member 7a, which slides easily in a guide Z fixed to the carrier 1;. On the lower part of the look ing member In there is mounted a locking pawl m, which leads to the stopping lever and which, while the apparatus is in action, is held in its raised position by a stop or a lug n as shown in Fig. 2.

On the upper part of the locking member is is mounted a roller 0,-which runs on the flanged edge 7'' of the disk e and as soon as it reaches the'gap z in this disk, can drop through it. I Then, as will be hereinafter described, the locking member 7a drops down.

The two disks cl and e which are adjustable relatively to the carrier 6 and to each othencan be connected together by appliances of any desired kind. It is essential that after they have been relativel adjusted they shall admit of being rotate together about the spindle c.

.This rotation is effected from the drivin mechanism of the main apparatus througfi any convenient gearing.

n the present case a so-called anchor catch p is provided which moves up and down in the well known way moving the disks (Z and 6 one tooth forward at the same time but preventing them from moving backward. When the toothed disk (I is being set, the catching action can be released in the well known way.

The method of operating the apparatus is as follows:

After releasing the catch of the disks the zero point of the diskd is brought u to the pointer 71.. Then the disk e in the ange f of which the pawl 70 with its roller 0 is mounted, is rotated. on the disk at until the pointer g is o posite the desired number of the disk d w ich the entire apparatus is to work to. The two. disks are then locked together, the anchor catch p engaged and the whole apparatus set in motion.

point as already above mentioned. The roller 0 then slides through the gap 21 and the locking member is drops down with it. At the same time the locking pawl m slides off the lug n, which latter then stops the whole apparatus.

It is obvious that a so-called adding mechanism of any kind may be combined with the present apparatus and the total amount weighed out by the whole apparatus may be checked by it.

I claim:

1. An apparatus of the class described comprising a disk, means for intermittently moving said disk, a peripherally flanged disk adapted to rotate with and being adjustable relatively to said first disk, the flange of said second disk being provided with a cut-away portion, a locking member, means on said locking member cooperating with the peripheral flange of said second disk for retaining the locking member in its inoperative position, a gap in said flange permitting the locking member to move t operative position.

2. An apparatus of the class described comprising a disk, the face of said disk being provided with graduations, means for intermittently moving said graduated disk, a second disk coupled with said graduated disk for movement therewith but capable of being adjusted relatively thereto, said second disk being provided with a peripheral flange, said flange being cut-away at one portion thereof, locking member slidably supportessee? ed adjacent said second disk, means carried by said locking member and bearing on said peripheral flange for retaining the locking member in its inoperative position, a locking pawl carried by said locking member, the cutaway portion. within the peripheral flange permitting the locking member to move to its operative position to release said pawl.

An apparatus of the class described comprising a disk formed with a series of peripheral teeth, means for rotating said disk, means for disconnecting said rotating means, a second disk provided with a peripheral flange, said flange being provided with a cut-away portion, said disk being coupled to said first disk for rotation therewith and flClJllStilblB relatively to said first disk, :1 locking member slidably supported adjacent said disks, a roller carried by one end of said locking member and adapted to bear against said peripheral flange to sup port said locking member in its inoperative position, a locking pawl carried by the other end of said locking lever, said roller adapted upon registering with the cut-away portion of the flange to allow the locking member to move to its operative position, to release said locking pawl,

The foregoing specification signed at l farburg, Germany.
